The aim of this study, therefore, was to obtain the data on Mokumao in order to find whether it is useful or not for improving the forests of this country. This research deals with an analysis of the relationship of the growth of various parts of trees from Northern Okinawa with respect to density of stand, wind, and soil influence according to the age of the trees. The analysis is mainly based on the sample trees collected from various forests different with respect to such facters as stand density, wind, and etc. 1. The growth of Mokumao growing lose to the sea is greatly influenced by the typhoons which usually come late spring and fall, and by the winter monsoons. The growth of this tree on the other hand is not greatly influenced by soil type and stand density. The younger trees are severely damaged by these winds.
